NVME-OCP-TCG-CONF(1)

💅 nvme-ocp-tcg-configuration-log — the NVMe Manual girlie edition 🌸

okay so bestie, welcome to the NVMe Manual page for nvme-ocp-tcg-configuration-log, aka the little command that goes and fetches the TCG configuration off your OCP-compliant device. it's giving ✨niche but iconic✨, and i'm gonna walk you through it like we're texting at 2am 🫶

🌈 NAME 🌈

nvme-ocp-tcg-configuration-log — retrieves the tcg configuration of a given OCP compliant device 💖

---

✨ SYNOPSIS ✨

nvme [<global-options>] ocp tcg-configuration-log <device> [--no-uuid | -n]

that's it, that's the whole vibe. short, sweet, slays 💅

---

🎀 DESCRIPTION 🎀

so for the NVMe device you hand over, this sends a tcg-configuration-log command and gives you back the tcg configuration log. literally its whole job, and it does it well 🔥

the <device> parameter is mandatory, no skipping it 🙈 and it can be either:

• the NVMe character device, like /dev/nvme0, or
• the block device, like /dev/nvme0n1

both work, pick your fighter 💜

⚠️ important vibe check: this only works on OCP compliant devices that actually support this feature. for any other device, the results are undefined — and not the fun kind of undefined, the 😭 kind. so please don't.

on success it returns 0. otherwise, you get an error code back. no cap, that's the whole deal.

---

💖 OPTIONS 💖

• -n, --no-uuid — do not try to auto-detect the UUID index for this command; it just defaults the UUID index to 0. sometimes you just wanna keep it simple, y'know? 🎀

---

👑 GLOBAL OPTIONS 👑

these are the big-girl options defined at the top-level nvme command, and yes, they're available to this subcommand too. main character energy fr fr ⭐

• --dry-run — prints the command that would be executed, but doesn't actually execute it. a little peek behind the curtain, no commitment 👀
• --no-ioctl-probing — disables probing for 64-bit IOCTL support.
• --no-retries — disables retry logic on transient errors. one shot, one opportunity 😤
• -o <fmt>, --output-format=<fmt> — sets the reporting format to normal, tabular, 'json, or binary. only one output format at a time, pick one bestie, you can't have all four 💀
• --output-format-version=<version> — selects the output format version. version 1 uses the original field naming, while version 2 (the default) gives you more consistent, script-friendly field names. other versions? rejected. not on the list, not invited 🚫
• --quiet — suppresses informational messages. errors still get reported, and --quiet cancels any --verbose for the library log level. the "shhh" option 🤫
• --set-options=<key=value>[,<key=value>...] — sets libnvme library options for this invocation. the supported keys are force-4k, mi-probe-enabled, test-base-dir and test-sysfs-dir.
• --timeout=<ms> — sets the timeout for the command, in milliseconds. infinite or -1 waits with no time limit (0xffffffff). patience is a virtue, or whatever 🧚
• -v, --verbose — increases the level of detail in the output, and you can specify it multiple times to get even more verbose. go off, be chatty 🗣️

also: these options can be set as machine-wide defaults in nvme-cli.conf(5), and a command-line flag always overrides the file. flags stay winning 👑

🦋 EXAMPLES 🦋

• has the program issue a tcg-configuration-log command to retrieve the 0xC7 log page. classic, iconic, no notes:

# nvme ocp tcg-configuration-log /dev/nvme0
